Weighing 110.03 carats, The Cora Sun-Drop diamond is said to be so valuable, that it’s priceless – literally. Experts consider the diamond so rare that it’s price cannot be calculated, and as of yet, no one has made an attempt to do so. This precious pear-shaped yellow diamond is approximately the size of a woman’s thumb and has a color grade of fancy vivid yellow, which is already extremely rare.  Unusual diamond of this color stem from very small amounts of nitrogen within the carbon structure of the stone. “When you look at a diamond like this you are not only looking at a unique piece of art, you are looking at the fascinating science that bought this stone to us,” said Alan Hart, head of mineralogy collection at The Natural History Museum. The stone is set to be on display for the next six months.
